Answer:

Step-by-step explanation:

Let's say "s" represents the number of steps you still need to take to achieve your goal of at least 12,100 steps. You've already walked 5204 steps, and if we add this to s, we should get a total of at least 12,100 steps:

s + 5204

The words "at least" means that we need to use ≥, so:

s + 5204 ≥ 12,100

The answer is E.

If we were to solve this inequality:

s + 5204 ≥ 12,100

s ≥ 6896

In other words, you still have to take at least 6896 more steps.

Step-by-step explanation:

Step 1: Find the inequality

So, we need to get more than or equal to 12,100 steps per day. If we already walked 5204, we need to walk another "s" amount to get more than or equal to 12,100.

We need to have "s" plus the amount of steps already walk which is 5204.

s + 5204

We need this part of this equation to be greater than or equal to 12,100

$s + 5204 \geq 12100$

Mean absolute deviation of 75, 89, 145, 85, 80, 92, 104, 90, 100?

Mama L [17]

First, compute the mean: $m=\frac{75+89+145+85+80+92+104+90+100}9=\frac{860}9=95.555$

Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445

Next we'll take the mean of these deviations: $\frac{20.555+6.555+49.445+10.555+15.555+3.555+8.445+5.555+4.445}9=\frac{124.665}9=13.8517$

The mean absolute deviation of your data is 13.8517

Help Pleasee Reflect shape A in the line x = -2

Cerrena [4.2K]

Answer: Check out the diagram below

The reflected image is shown in red.

=================================================

Explanation:

Draw a vertical line through -2 on the x axis. This is the mirror line.

Now focus on the upper right corner of the figure, which is at (-3, -1). Notice how the horizontal distance from this corner point to the mirror line is exactly 1 unit. If we move another 1 unit to the right, then we'll arrive at (-1,-1) which is where the reflected point lands or ends up.

In short, the upper right corner point (-3,-1) reflects over x = -2 to land on (-1,-1)

----------------------

As another example, the upper left corner point (-5, -1) will move exactly 4 spaces to the right to get to the mirror line. Then we move another 4 spaces to the right to get to (2,-1).

So the upper left corner (-5,-1) will ultimately move to (2,-1) after the reflection over x = -2.

Apply these steps to the other corner points and you'll end up with what is shown below.

Take note that a point like A(-5,-1) moves to A'(1,-1), and similar to the other points as well. Also, notice that when going from A to B to C, etc we are moving clockwise. We move counterclockwise when going from A' to B' to C' etc. Reflections always swap the orientation.
